Hi all Anyone know if all the 10 species of Taxus are variable in levlels of alkaloids however they all have red berrys but ive noticed that some Taxus baccata cultivars have orange or yellow berrys. Thanks for any information
The arils (berries) are non-toxic anyway, regardless of colour. It's the seed, needles, and bark that contain taxanes. I can't comment on taxane concentrations in various species though I have read that it can vary quite siginificantly in a single species (T. canadensis in this case) due to genetic variability.
